696 Engine modifications

The nemisis is expensive, around 1000 last I looked.  It is an ecu replacement though, so you would not need to get the DP ecu.  The power comander does have a big advantage in that everyone knows how to tune them and maps are easy to find.  But it does tend to "fight" the o2 sensors on newer bikes requiring o2 elimiators or the DP ecu at extra cost.

the dp ecu eliminates the o2 sensors altogher right? so with the PC V it should work great?

As far as I know it does, some one may correct me on that though.

afaik the siemens dp ecu are all lambda enabled.

maybe you could turn it off using the aprilia tool - i'm not sure if the axone will talk to it as an aprilia, haven't got to try yet.

tell me more about this aprilia tool?

When I got my 50cc tuned, the boys in the shop plugged in their Game Boy.
I have no idea, but maybe this is something close to what Brad is talking about

I also like your project. It has some great potential. I have a 2 into 1 undertail exhaust you may like. Still working on the tank skin though.

i am interesting in the mid pipe you used to go 2-1. i already have some mufflers coming, and i also have a second complete exhaust system to work with a couple of ideas.

i could run stock, 2-1, 2-2 or 2-2 with a cross pipe.

Ryan has a 2-1 that comes up high under the center of the bike.

i'm going to try a 2-2 tucked high under the tail. if there are issues i'll try the same setup with a cross pipe at the same location as the current Y pipe.

the apirlia tool is the axone, someone else's version of the dds sort of thing.  the game boy (a real game boy) was used for some of the scooter models.

the 2004 on rsvr's come with a seimens ecu, but i'm not sure if it's similar to the 696 ecu in terms of ecu itself, software or diagnostic procedure.  with the aprilia ecu you can turn off the lambda input and remove the sensor (never actually tried it) or switch to a second pre loaded map that is the open muffler, open loop map.  so if you fit pipes you don't need to replace the ecu, just change the enabled map.

oh so now someone tells me... DP ecu is already on the way.

and i am picking up a pair of spare 696 heads to try my hand at polishing the ports myself.

  Good on ya.  Hope you can post before and after pics?

[Raux]

well i've done some more figures.

i think the volumetric efficiency of the stock 696/796 heads is about 79%
i've got to hit about 94% to reach my goals

with the 803cc that may give me numbers of 95hp and 69 lbft of torque at the crank (81hp at the wheel)

with the stock 696 being 80/50 and the 796 being 81/59 that's about 18%/37% and 17%/17% relative increases.

of course this is all mathematical and not practical application. i'm sure i won't be able to specifically increase the VE 15%. but who knows.

I like numbers.

FYI, Ducati changed the official horsepower to the below.  They did it sometime between last Fall, this Spring.  Maybe they did it knowing they would be releasing the MiniTard & it officially making 81hp?

Power*:     78.8 hp - 58.8 kW @ 9000 RPM  
Torque*:  50.6 ft-lb - 7.0 kgm @ 7750 RPM  

I like your numbers too.  I'd be interested in how you make out.  As soon as the 796 was announced & I realized I could turn my 696 into an 800, I've been thinking about it.  Add that to the fact that the heads on our 696 are much better than the ones used on the s2r800, they could produce alot of power.

And by 'better' what do you mean? I have the S2R800, could i gain more power by adding 796 or 696 heads?
Curious...

My understanding is the heads on the 696/796 are designed like the 1000/1100DS heads.  In fact, the 696 is still a 695cc motor, but due to the new head design & increased intake/exhaust flow, Ducati went with the 696 label to differentiate between the two.  696(78 or 80hp, not sure, I've seen both) makes more power than a 695(72hp).  If Ducati's numbers can be believed, the 696 actually makes more power than what the 2007 s2r800 (77hp) was listed at.  FYI, bore size is the same on the 696 & 800, so it might be feasible to get it to fit.  That's what got some of us thinking about fitting the crank from an 803cc motor to the 696.
